Damage caused by road accidents is an important and significant issue, since it poses a significant challenge to the general public's health. Including trauma due to trauma in crashes can be a fracture of the ribs due to impact on the chest wall in front of the collision. In this thesis, using multi-functional dynamic modeling, the driver's behavior in response to the collision at different speeds and different angles of the seat back is examined so that according to the important parameters of occupancy of the occupant, the amount Evaluate the effectiveness of the proposed multifunctional model in preventing injuries in comparison with experimental results. To this end, we first introduce the proposed model and according to different parameters, the governing equations of motion are obtained using the Lagrange method. Finally, the effect of the seat belt closure by modeling its applied force to the driver at different speeds And the back angle of the fixed seat compared to the non-belted seat mode. Finally, it was shown that the diagrams resulting from the modeling have a great deal with the results obtained from the simulation and the experimental work, as well as the severity of the damage The injuries to the chest have a direct bearing on acceleration.
